What is the molarity a 3.2 L aqueous solution with 12g of KCl

0.05M

Explanation:

Mass=12g

Volume in liters =3.2L

Molecular mass of KCL=1x39.0983+1x35.453=74.5513

Number of moles=mass ➗ molecular mass

Number of moles=12 ➗ 74.5513

Number of moles=0.16

Molarity=number of moles ➗ volume in liters

Molarity=0.16 ➗ 3.2

Molarity=0.05M

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.

explanation:

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
